spi - 7ct3 25p10vp

Thank you for the quick reply sir, I have located it.
Would you happen to know if it is necessary to downgrade or upgrade after replacing this on the new board?

Also why is it needed to downgrade or upgrade after switching the SPI? Thsnks for your ideas, I appreciate it very much.

over all TVs based Linux firmware... the panel configuration and RC too saved at first step start script on SPI Flash, which it write it on NAND (EMMC) at panel or gamma config partition if they are not exist.

after exchange the spi IC and downgrade or upgrade we will teach the component on each other to communicated as sector base.

The main firmware is in NAND 29F8G08ABABA, the bootloader is in SPI, the settings are in EEPROM 24C64.

Aahh oke I see, thank you for the explanation.

How do I perform the upgrade or downgrade?

sorry lotas ... this is new to me... then where are the config which make TV response to RC and displaying logo on screen..??

In Nand and Eeprom

In Nand and Eeprom

in general there are no call of eeprom and spi at tv same time. spi flash are the master boot... nand (emmc) are the firmware keeper regrades of the main IC response..
MFC of panel paramter will be saved on exrta flash. op on t-con or on MB to handle the panel specification.

from the look at this TV firmware we don't find MFC section... means are all in one SPI. look at the MB and see which HW installed and what kind of FW used.. this is a main keys at any tv to know if we have HW or FW issue.
